FIELD OF THE INVENTION

The present invention relates to a sports luggage. More particularly, the present invention relates to a sport luggage that is collapsible for storage, transport, shipping and/or handling purposes.

BACKGROUND OF THE INVENTION

Athletic equipment bags, or sports bags as they are often commonly referred to, have become increasingly popular in numerous sports because of their functionality and attractiveness to athletes. They are typically quite large, however, in order to allow a sports participant to carry all the equipment he or she needs for games and practice sessions. In this respect, a hockey player, for example, may require his or her sports bag to carry at least one stick, a pair of skates, a helmet, gloves, shoulder and shin pads, elbow pads, pants, a jersey, neck guard, socks, athletic support, etc. Goalies need even more equipment, as they have to transport large goalie pads as well.

Heretofore, conventional sports bags generally include two types. The first original type is made from soft material (nylon, canvas, cloth, or leather, for example), is not capable of maintaining a given shape and volume per se, and cannot protect the storage items against impact. Not only does such a soft bag provide an awkward means of transporting equipment, but it is typically very difficult to find a particular piece of equipment within such a large carry bag as they typically are not compartmentalized. In fact, it is often necessary to rummage through all the equipment held in such bags (which necessitates the removal of much of the equipment from the bag) while a search is made for a desired article.

The second type of sports bag has a rigid or semi-rigid support structure, often having an outer, substantially rigid cover structure to provide greater support and to prevent items within the bag from being damaged by compression or impact. However, because of the large size of such bags, ideally, when empty these bags should have the ability to collapse in size for storage, transport, shipping and/or handling purposes. It is therefore an object of the present invention to provide a sports bag that has the ability to collapse in a space efficient manner, and whereby the bag provides for ease of set-up and collapsing for users, transporters and handlers of the bags alike.

The second embodiment has support braces 14 (which may be fabricated from a sturdy, flexible carbon fibre or composite material such as pultrusion fibreglass with glass-fibre reinforced polymer or plastic material comprising epoxy, a thermosetting plastic (such as polyester or vinylester) or thermoplastic or other material(s) as would be known to persons skilled in the art that provide sufficient structure when set up) that are fully secured to frame 17 or to the rear or side panels of case 10 via holders 13. These holders 13 may be fabricated from plastic, fabric, metal, or synthetic materials, such as synthetic plastic material (e.g. polypropylene or polyurethane). The support braces 14 extend generally from the upper rear corner areas of rear frame 17 to the lower front corner areas of soft front portion 11 (when seen in an open position). A person skilled in the art may wish to incorporate further braces that extend vertically from the lower rear corners to the upper rear corners inside the bag as shown in FIG. 7, and such braces may also engage at upper ends thereof with holders 13. Such further braces could be made of the same materials as used for braces 14.

FIG. 8 shows the front portion 11 opened up, and again shows floor panel attachment means 7 (preferably Velcro or other means as would be known to persons skilled in the art) and support feet 6, which supports the floor panel 4 and takes pressure off the braces 14 when the bag is under stress. The arrow indicates the direction of placement of floor panel 4 to secure the floor panel to the soft base material that makes up the bottom of bag 10 by means of floor panel attachment means 7 (e.g. Velcro). Once secured, the floor panel 4 is positioned on top of the support feet 6.

FIG. 9 shows a final step (that may or may not be necessary) that includes securing the floor panel 4 via fabric flaps 15 that are preferably sewn to the soft front portion 11 and bottom of the bag respectively. These flaps 15 secure over the floor panel 4 with Velcro or other similar means as would be known to persons skilled in the art. FIG. 10 shows the second embodiment in a fully set-up position.

FIG. 11 shows a third embodiment of the present invention which again comprises a main luggage case 10 with wheels 16 on the bottom thereof. The rear portion of the main luggage case 10 has a structural frame 17. The front portion 11 of the main luggage case 10 is preferably comprised of a soft fabric case extending from the frame 17 of the main luggage case 10. The third embodiment has rotatable support braces 19 (which may be fabricated from a sturdy, flexible carbon fibre or composite material such as pultrusion fibreglass with glass-fibre reinforced polymer or plastic material comprising epoxy, a thermosetting plastic (such as polyester or vinylester) or thermoplastic or other material(s) as would be known to persons skilled in the art that provide sufficient structure when set up) that may be releasably and frictionally engaged at one end within rotatable tubes 18 (which may be fabricated from rigid fibreglass, plastic or composite material, for example, but are preferably made of steel or similarly strong material to provide support for when heavier items such as goalie pads are to be hung on case 10), and that may be secured at their other end via holders 13. Braces 19 and tubes 18 provide the necessary structure to the bag when the bag is in an open set-up position. A person skilled in the art may wish to incorporate further braces that extend vertically from the lower rear corners to the upper rear corners inside the bag as shown in FIG. 11, and such braces may also engage at upper ends thereof with rotatable tubes 18. Such further braces could be made of the same materials as used for braces 19.
